Objective: Research on treatments for children with avoidant restrictive food intake disorder (ARFID) is needed. This pilot case series describes outcome data for 20 children ages 6-12 years old with a diagnosis of ARFID and who are low-weight.
Method: Participants were recruited nationwide as part of an ongoing randomized clinical trial. All participants in this study received a 14-session psychoeducational and motivational treatment (PMT) protocol. Parents completed measures of ARFID severity (the Pica, ARFID, Rumination Disorder Interview) and parental self-efficacy (Parents vs. ARFID scale). Height and weight were self-reported by parents and percent of estimated body weight (%EBW) was calculated. Assessments occurred at baseline, 1-month within treatment, 2-months within treatment, end-of-treatment (EOT), and 6-month follow-up.
Results: Twenty children (10.34 ± 1.76 years; 85% Non-Hispanic; 75% White; 70% female; 84.16 ± 4.66% EBW) with low-weight ARFID and their parents received PMT-ARFID with a clinician specializing in eating disorders. By EOT, PARDI severity scores decreased (large effect size) parental self-efficacy increased (medium effect size), but %EBW remained unchanged.
Discussion: Additional research evaluating PMT in adequately powered clinical trials for youth with ARFID is needed.
